@David LitzauYour numbers seem fair and it’s really nice that the lease is extended until 2020.

They are both fairly close to downtown (8 min or so)Property A is probably worth around $350kBoth sides rented = $2225 (which is actually decently high for the home and area)Property B is hopefully worth around $500k once the rehab is complete (we bought for $332 in abysmal condition, I don't know how we passed FHA inspection  .... :) )Property B would rent for probably $3500 total ($1650 for the smaller side $1850 for the larger side)Neither will ever come close to earning $1k of rent per $100k of home value so seems to make sense to try and take that equity and spread it out into properties where it can earn more rent, even if those properties aren't appreciating like these two seem to be.

The MLS will have the most up-to-date information, but I've found Redfin to be a good alternative as it has a fair amount of the same information as the MLS does.

There are a lot of ways to skin the cat, the best outcome for you is knowing all the angles and choosing the most appropriate to YOUR situation.Along the same line of thought, For the HVAC unit, Assuming the tenant is paying the utilities.

Sounds like your parents actually want to sell at fair market value, but think that if appears as if they are selling for less you will somehow be able to obtain a larger loan in 13 months.

Meanwhile, if I were to hire a public adjuster, they would have my best interest in mind and make sure that I'm treated fairly? 

A fairly new decent 4 bedroom 3 bathroom house was sold for only $35,000. (2426 Gilbert Dr SW, Atlanta, GA 30331).

They have more skin in the game then you do.Make sure you get clear title.

I think the point is that the council tasked their employee to work with the citizens and she listened to both sides and spent several months putting together a very fair piece of regulation. 

@Jon MarkThe seller needs you to have "skin in game".
